Adrafinil Side Effects

The side effects of adrafinil largely mimic the side effects of modafinil. The two drugs have identical side effects because adrafinil is converted to modafinil in the body. Adrafinil is not itself biologically active in the brain - modafinil is the active metabolite.

Swelling, belching, decrease in appetite, vomiting, tingling, burning, or prickling sensations in the skin, difficulty having a bowel movement, dryness of the mouth, diarrhea, sour stomach, flushing or redness of the skin, feeling of constant movement of self or surroundings, heartburn, muscle stiffness, stuffy or runny nose, sores, ulcers, or white spots on the lips or in the mouth, back pain, indigestion, dryness of the skin, stomach discomfort upset or pain

There are a few key ways you can mitigate adrafinil's side effects.

First, make sure that you're not inadvertently taking a drug that interacts with adrafinil.

Modafinil is metabolized by hepatic amide hydrolysis, but the liver enzymes CYP1A2, CYP2B6, CYP2C9, CYP2C19, CYP3A4, CYP3A5 also play a role. Hence, any drug that's also metabolized by one of these cytochrome enzymes can interfere with the metabolism of adrafinil and worsen side effects.

Second, follow best practices while using psychostimulants. In other words:

Get plenty of rest. It's tempting in our productivity obsessed culture to use modafinil/adrafinil to get away with less sleep. This is counterproductive because a great deal of learning takes places during sleep. Sleep is necessary for memory consolidation.
